Trivia

Specially made footage was used for the "Who's That Engine?" segments.

In the Dutch dub of the series, the segments are called "Alle Locomotieven Verzamelen!", which translates out to "All Locomotives Gather!".

In the "Who's That Engine?" segment featuring Thomas, one of the clues Sir Topham Hatt uses to describe him are "six small wheels, a short stumpy funnel, and a short stumpy dome," which is a direct reference to the first season episode, Thomas and Gordon.
